Stuck in fastboot - Google Pixel 4 XL Questions & Answers

Yes, it is my own fault. I rooted yesterday, and installed a kernel today. All was fine until I tried to update to to the November update, never got that far.
I made sure to use the correct factory image for Magisk.
In adb i typed fastboot recovery, and my is now stuck on the google splash screen.
I can boot to fastboot, with the power button, and down arrow, and that's it.
fastboot devices, in adb does return the serial number.
I am unable to get beyond that. I know I'm softbricked.
Any suggestions would be appreciated.

Seems like you should be able to side load factory image

After about 20 tries, I was finally able to boot to recovery. I'm going to factory reset, and redo. Thanks for the help, though.

Here is an update:
When I run adb devices, the serial number is not returned.
When I run fast devices, the serial number is returned.
I have extracted all the files from the zip, for the image, there is no boot.sig, recovery.img, system.sig, or vendor sig.

In adb mode in the OS, try typing..adb kill-server...
Then allow your device to always communicate with your pc, your having a driver issue. Your readout for your factory image is correct. There is no recovery anymore, it's tied in with the boot.img

@mimart7
If you booted fastboot mode, fastboot devices is all that is needed to insure your phone is communicating with your computer.
Are you using the latest SDK platform-tools 29.0.5?
If yes, is the Platform-tools, and the extracted factory image files in this folder C:\Platform-tools\New folder?

I've got it working, thanks to all.

Did you have:
USB Debugging enabled?
Do you have Platform Tools?
https://developer.android.com/studio/releases/platform-tools
When in fastboot, and your phone is attached to your computer, and you type fastboot devices in adb, do you get your the serial number of your phone?

I'm in this situation and yes I have the lastest platform-tools. I do get the serial number back when I type fastboot devices. My folder location is C:\Platform-tools

Yup SDK r29.0.6.
I was soft-bricked and stuck in a boot loop.
I managed to get to recovery mode but only by flashing all the files then holding the power button & volume up button.
Once in recovery, I tried a million things to figure out how to get it back to a clean slate.
After hundreds of tries, I managed to sideload flame OTA.
The phone's bootloader is now unlocked.
Now going to focus on what I did wrong originally when trying to get Magisk on the Pixel 4 :laugh:

How to flash CWM Unoffical???

Hi,
I downloaded CWM unofficial 6.0.32 from this forum, but I'm new and I have no idea what to do with it. I did successfully root my phone that's all I've done to it.
Thanks!
You use fastboot commands. There's a tutorial skeevy just made in general.
Sent from my PACMAN MATRIX HD MAXX
I'm sorry, but I'm getting stuck
1: I installed the sdk replaced the files with the updated ones provided.
2:checked adb devices from command promt and It sees my device.
3: ran adb and it successfully starts
4: I then rebooted phone into fastboot Power+Volume down and adb reports device not found.
5: pull hair out.
I'd appreciate a sort of idiots guide because I'm getting no where fast and I've read and read, but they don't explain much that's the problem.

4 You're in fastboot mode....adb won't recognize your phone....that's normal...

use the command "fastboot flash recovery cwm.img" from inside the folder with cwm.img. Or move the fastboot executable and the recovery image to C:\ and do it from there...Win can crap out when/if there are too many characters in the path...
Also, right click the fastboot executable and set it to run as admin. Might have to disable UAC as well....don't ask me how, I don't know...google it.
//I'm cereal, ya had to rename the SBF because in the home directory the path + sbf name would be too many characters for Win to work with and the flash would fail....
No idea, but here's what I did to install cwm. download safestrap apk, boot to safestrap recovery, hit fix permission, go back to cmd prompt, fastboot flash it,
edit: try enabling "usb developer/debugging mode" before booting it into fastboot?

You might have a picky motherboard. Some front-side ubs ports won't work for some odd reason for some users. Use a usb port on the back of your pc.
Out of curiousity, did you try flashing a fastboot with rsd before you started doing this? And if yes, did it finish completely?
Also attached is a zip to flash CWM from SSR (maybe...SSR might block the command) and a fastboot modified to only flash CWM. Both are untested but worth a shot.
EDIT: Any one of you windows users care to chime in? Ya'll know I don't run it. I'm kinda runnin outta ideas here....gettin down to the just use linux reply...

[RESOLVED]Did I just brick my phone? Any help at all is appreciated

So in preparation for the kitkat update, I did the following steps:
unrooted within superuser app
flash stock recovery
flash stock boot.img
flash stock system.img
Once I rebooted I downloaded the OTA and tried to install. Now, after that, I wasnt really sure what happened on the phone, as I passed the time by watching a youtube video on my computer. However, I looked back down, and it was inside the bootloader, giving a partition failure of some sort. And when I tried to flash anything, it gave a remote failure error. It won't boot into anything, and it says the device is locked. Can't do mfastboot oem get_unlock_data either, literally nothing but fastboot reboot works
do i have a $650 paper weight on my hands?

Well fastboot starts at least. If you try to reload stock firmware (4.2.2) using rsdlite(not fastboot from a command line) which error do you get?

My device isn't showing up under rsdlite 6.1.4 at all
Sadly then I'm leaning towards it being a pretty looking brick. I've had many flash failures while experimenting with my XT1058s but I have never tried any custom recoveries so they were always recoverable with fastboot and rsdlite.
Hopefully someone else has some suggestions for you to try.
I flashed system.img, recovery.img, and boot.img from the original sbf file. not from the first OTA. and then the phone seems to have locked itself

Had you taken the first OTA already? If you had done that, you should have flashed these files from the new SBF file....
So, when you are in fastboot mode, your device is no longer getting recognized from fasboot command line? What does fastboot devices show?

After that can you try any of the fastboot flash commands using the new SBF file?

Hi friends,

i wanted to root it and installed carrera 2.8 twrp with fastboot mode but nothing changed.i could not get twrp.so i could not install supersu and i wanted to install CRR-L09C432B145 rom and my device get bootloop.
So i tried to install other roms via fastboot but nothing changed.
Then i gooogled all the net and did everything but i could't get device back.
i wanted to install twrp rtecovery but i think there is a problem and no rom or recovery got installed.
Now:
1-i don't know which rom was installed on it.CRR-L09C432B161 or something else.
2-i can not install any rom or recovery.(i did many times to extract with Huawei extract tool cust,boot,recovery,system and installed with fastboot but nothing)
3-My device's bootloader is unlocked but i don't know FRP is locked or unlocked(the pic is under)
4-Maybe FRP is locked and i can not install anything becouse of it,i do not know
5-My compuer can't load the device,all the adb drivers installed,no problem.i changed cable and sd card but same problem.
Please help me.i can not use my device.

The Fastboot picture is to small. Can´t read what´s written there but i guess your device is FRP locked since there are two red texts/lines on the bottom side.
The only thing you could try is placing the right Update.App on an SD card and do an forceupdate via Vol+/- and Power. Since you don´t know the original Build, you have to try different files until one works.

Hi,thanks for your reply,
i tried many times that solution.when i do volume+/ and power device get Huawei's erocovery and i press the "update with internet" it says "no wireless found".the other alternatives are "power off" and "reset".
PS:Yes,you're right in the second image,it says:
PHONE Unlocked
FRP Unlock
with red color.
If there is "PHONE Unlocked" and "FRP Unlocked" written on the Fastboot screen, you can flash a new system. Extract System.img Recovery.img boot.img and cust.img from an Update.App and flash via fastboot. To be able to do that, you should search for "Minimal ADB and Fastboot Driver" in the XDA Forum and instal that.

ADB drivers all installed.Phone unlocked but it says "FRP Unlock".Not FRP unlocked.i flashed many times new system. Extracted System.img Recovery.img boot.img and cust.img from an Update bu nothing changed.i think they can not installed.
i tried many different roms..B145,B321,B114.And i tried to install twrp recovery but nothing changed again.
i tried all adb command to erase local stroge but isays the command are false.
and i forget to say:my computer can not see the device.it says "device not found".i uninstall the adb drivers and install again the last driver but nothing changed.
Any other way to install rom?
Or if i have to unlock FRP can i install rom?i don't know muck more about the Huawei system.
i upload images again.
You have to use fastboot commands in fastboot Mode. ADB commands wont work. Plug in your Phone. Open device Manager on your pc. Look for "android device". Remove Driver. Unplug Phone. Install "minimal adb and fastboot". Reboot pc. Plug j. Phone. Pc should find Phone now.
Minimal Adb and fastboot drivers also installed.My device shown like this at the device manager.
And i wrote wrong i tries always fastboot commands,sorry.

Question Oneplus 10 Pro stuck in Bootloop

So I restarted my phone today and it just entered an infinite boot loop. Not sure what happened but that's all it's doing whenever I turn it on. I can enter the bootloader but other than that nothing is working. I noticed the bootloader and baseband are empty as well.
I wish this phone had an unbrick tool like the oneplus 7 devices but I don't know. I guess I may just have a brick until someone shakes.

That's not good usually one or the other fixes it. Only thing I can think of is flashing all images in fastboot. But try vendor_boot first
When this happened to me on my OP6 when I had it and when I couldn't recover it with MSM tools or boot.img, I decided it is motherboard failure.
But I would try fastboot ROM if I were you. If it doesn't help, I will send it to the service center.
You may have booted a patched yet not made it permanent so when you rebooted you lost it.
If that rings a bell then just boot a patched boot image. Not flash.. once you're booted and in the system just open magisk and click direct install..
Reboot and it should be permanent.
Beyond that you can go to recovery or fastboot to get back in business although you'll lose your data
My phone did this once when I accidentally changed A/B partition, try switching partition via fastboot
Do the following
fastboot getvar all
then you'll get somewhere the following
(bootloader) current-slot:A or B
then you should be able to do either
fastboot set_active other
or either
fastboot set_active a
fastboot set_active b

That means you have no boot img on it
try to flash a boot img to slot a and slot b
Is this still ongoing?? Lol that's insanity.
The reason you cannot boot is 100% your boot image.
So either boot or flash a boot image (stock or patched)
If you'd like to reflash your whole phone then click on vol up and then recovery.
If you're looking for a tool then grab fastboot enhance, whilst in fastboot use it to remove the cow files, search for them, once that's done, flash a payload.bin and this will reload your whole OS.
There are guides for everything I've mentioned above, just search.

Hi,
I have the same problem. Never used the phone. Just to install Magisk and edit the payload.bin file. When I installed the new boot file via Fastboot it went wrong.
Tried everything but can't get the phone out of the loop. I don't have a recovery function!
You indicate that there are manuals for existing solutions everywhere. Do you have the links for me? Not very good at finding this.

Doesn't help that the forums went through a crap update that broke the sections.
That being said, you're looking for a guide so that's your key word.
(Guide) Rooting, payload dumper, magisk_patched guides NE2213
Hi all, Thought i'd share a guide on how to get these boot images yourself as well as all the files required, plus the patched boot.img if you just want to go ahead and boot/flash it without obtaining one yourself Please read the process before...
forum.xda-developers.com
There's a good few of them, the screen shot is taken from the main OnePlus 10 pro forum section, I can see two. Mine and the 2215 one.
Also when you say 'installed' I hope you meant boot and not flash, booting is risk free.. Read my thread and it'll make sense.
I wish people would read more...cause it all here...just need to take the time and read alot of post...to find what they are looking for...lol

This is probably the cause of the issue. Magisk switched your active slot to the previous one which becomes unbootable after the update completes successfully. You should be able to switch back to your working slot by doing fastboot --set-active=other, although I'm not 100% sure this is right solution I think it's a reasonable one. I'm always a bit scared suggesting solutions to people who have a recent OnePlus phone since they can't unbrick it if they end up in a hard brick.

Is your phone in bootloader mode and recognized by fastboot? Can you send a screenshot of the command + error?

Boot the Magisk patched boot.img (don't flash it!). Then go into Magisk and do a direct install (DON'T do install to inactive slot). Then reboot and check if root is still there.

You can use the one you already have, you just need to do fastboot boot magisk_patched.img (or whatever it's called) instead of fastboot flash.

Are you sure you're in bootloader mode and not fastbootd?

adb reboot fastboot reboots you to fastbootd, not bootloader mode! You need to do adb reboot bootloader.

OK, finally everything worked. I'm a little bit rusty (my first android was HTC desire back in 2010).
Thank you very much, You really saved me a lot of time and frustration !!! I already started to think how to get all the data back.
I really appreciate your help !!!
THank you again.
Lior
